TCPConnect timeout

JohnMC · February 1, 2009

i belive that Kips will still hang on an invalid tcpconnect for ~10 seconds before fail, i need something that A. return imediatly and the status can be checked on, or a way to adjust settings that are embedded into TCP... i vote for the earlier... this winsock stuff is the way to go, im building a UDF to replace TCPConnect and TCPSend (i cant figure out anyway to use autoit TCPSend with the winsock TCPConnect) but im not a pro with this stuff so any help would be apreciated, here is what i have:

Global Const $SCKTCPPROTOCOL = 0
Global Const $SCKUDPPROTOCOL = 0x01
Global Const $SCKCLOSED = 0
Global Const $SCKOPEN = 0x01
Global Const $SCKLISTENING = 0x02
Global Const $SCKCONNECTIONPENDING = 0x03
Global Const $SCKRESOLVINGHOST = 0x04
Global Const $SCKHOSTRESOLVED = 0x05
Global Const $SCKCONNECTING = 0x06
Global Const $SCKCONNECTED = 0x07
Global Const $SCKCLOSING = 0x08
Global Const $SCKERROR = 0x09

Func _TCPStartup()
    FileInstall("_OSWINSCK.dll",@scriptDir & "\_OSWINSCK.dll",1)
    FileInstall("_OSWINSCK.txt",@scriptDir & "\_OSWINSCK.txt",1)
    $runstring = "regsvr32 /s """ & @scriptDir & "\_OSWINSCK.dll"""
    $status = RunWait(@ComSpec & " /C " & $runstring, "", @SW_HIDE)
    return $status 
EndFunc

Func _TCPConnect($sAddr, $iPort, $iTimeout=100)
    Local $oSocket, $timer
    $oSocket = ObjCreate("OSWINSCK.Winsock")

    $oSocket.Protocol = $SCKTCPPROTOCOL; set protocol to be tcp
    $timer = TimerInit()
    $oSocket.Connect($sAddr, $iPort)

    While 1

        If $oSocket.State = $SCKERROR Then
            $oSocket = 0
            Return -2;connection error (will give up for now)
        EndIf

        If $oSocket.State = $SCKCONNECTED Then
            Return $oSocket; return object for connection
        EndIf

        If TimerDiff($timer) > $iTimeout Then
            $oSocket = 0
            Return -3; connection timeout
        EndIf

        Sleep(20)
    WEnd

EndFunc

Func _TCPSend($oSocket,$sData)
    $oSocket.SendData($sData)
EndFunc

the issue is that i dont see how to return the amount of data sent

other then that it works great, just need a socket close function

JohnMC · February 2, 2009

ok so i dove in a bit on this COM stuff, but now im stuck, i just cant figure out how to retrieve recieved data

Func _TCP_OnDataArrival($Len)
    While 1
        $data=$ConnectSocket.GetDataBuffer
        If $data<>"" Then ExitLoop
    WEnd
    MsgBox(0,"Len/Dat",$Len&@CRLF&$data)
EndFunc

or

Func _TCP_OnDataArrival($Len)
    While 1
        $ConnectSocket.GetData($data,"vbLong",1024)
        If $data<>"" Then ExitLoop
    WEnd
    MsgBox(0,"Len/Dat",$Len&@CRLF&$data)
EndFunc

object.GetData(data, [vtype], [maxLen])
Retrieve data sent by the remote computer (acceptable values for vtype parameter are vbByte, vbInteger, vbLong, vbSingle, vbDouble, vbCurrency, vbDate, vbBoolean, vbError, vbString, vbArray + vbByte)
object.GetDataBuffer()
Returns data sent by the remote computer (For use in Javascript and similar languages, not supporting return parameters in functions)

the above functions are successfuly called when the data is recieved, and without the while loop $len will return the proper length, but i just cant GET the data... as you see in the quote from OstroSoft, object.GetData has some parameters, and im not sure if ive used them right.... any ideas?

Try this, it cycles from 100ms to 500ms in 50ms steps. On my local lan connecting to a telnet server, 100ms port timeout is reliable. For yahoo reliable connection requires port timeout > 200ms.

I wrote a port scanner like this:

Compile this to Scan.exe

#NoTrayIcon

If $CmdLine[0] >= 2 Then
    $myip = $CmdLine[1]
    $myport = $CmdLine[2]
Else
    Exit
EndIf

TCPStartup()
TCPConnect($myip, $myport)

Func OnExit()
    TCPShutdown()
EndFunc

Hope that helps

Authenticity · February 2, 2009

the above functions are successfuly called when the data is recieved, and without the while loop $len will return the proper length, but i just cant GET the data... as you see in the quote from OstroSoft, object.GetData has some parameters, and im not sure if ive used them right.... any ideas?

The value for the second parameter should be the constant of the value I believe:

vbByte = 17

vbInteger = 2

vbLong = 3

vbSingle = 4

vbDouble = 5

vbCurrency = 6

vbDate = 7

vbBoolean = 11

vbError = 10

vbString = 8

vbArray = 8192

So vbArray + vbByte is 0x2011.

JohnMC · February 2, 2009

Dampe, thank you for that idea, if i cant get this working shortly i will use that method for sure

Authenticity, thankyou, i had been looking for this, i figured no way in hell was i suposed to use a string to detemin the data type, however i guess i just to catch on quick enough, would it look like this:

Func _TCP_OnDataArrival($Len)
    While 1
        $ConnectSocket.GetData($data,0x3,1024)
        If $data<>"" Then ExitLoop
    WEnd
    MsgBox(0,"Len/Dat",$Len&@CRLF&$data)
EndFunc

because i already have a Const $SCKCONNECTIONPENDING = 0x03

sorry if this leads to a noob style lesson in conversion!

if the above is correct, it still doesnt work, OSWINSCK will call this function on data arrival like it should, it will set $Len like it should, but the data does not get inserted in $data, it just loops.

Authenticity · February 2, 2009

Few things:

What you should send depend on what the function expects to receive, so it might be the value of vbLong for example or the type name of it, if it's so then you'll need to send a string like "Long" or "Currency" for long or currency types respectively.

You can declare as much global const with the same value but different names like -> Global Const $vbLong = 3.

The problem IMO is that you're sending maxlen parameter as 1024 but expect to retrieve only 4 bytes, use array instead.

JohnMC · February 3, 2009

thanks for continuing to help, im trying very hard to learn this...

ive tried every data type and combination of code i can think of.. just to make sure im not crazy i tried to make this code in js and it works! so here is the js code that works and the autoit code that fails

oWinsock = new ActiveXObject("OSWINSCK.Winsock");

WScript.ConnectObject(oWinsock, "oWinsock_");
oWinsock.Connect("192.168.0.1","2021");

function oWinsock_OnConnect() {
  oWinsock.SendData('TESTJAVA[-]PING');
}

function oWinsock_OnDataArrival(bytesTotal) {
  var sBuffer = oWinsock.GetDataBuffer();
  WScript.Echo(sBuffer);
}


WScript.Sleep(3000);

$oSocket = ObjCreate("OSWINSCK.Winsock")

ObjEvent($oSocket, "_TCP_")
$oSocket.Connect("192.168.0.1",2021)

Sleep(3000)

Func _TCP_OnConnect()
    $oSocket.SendData("TESTSCRIPT[-]PING")
EndFunc

Func _TCP_OnDataArrival($Len)
    $data=$oSocket.GetDataBuffer()
    MsgBox(0,"Data",$data)
EndFunc

i just dont get it, its the same!

JohnMC · February 3, 2009

btw... again autoit will send the data properly, and the $len variable is correct (its the length of the string returned)

any ideas? could this be a bug or incompatability? it seems black and white to me, i dont see anything i could do different in the autoit script

Yeah, lol you tell me...

I'm toying around with this object. Give me a few minutes I'll break this mother... What you need first before attempting to go further with the client is sort of Do...Until $oWinsock.State = 7 and exit the program if it takes more than 5 seconds to get this state.... I'll keep testing.

Edit: Heh, JohnMC I'm almost there... crossing my fingers

Edit: Meh, I'm done with this. Can't find a clue of what is wrong with this one. Use TCP* instead... much better for socket communication than OSWINSCK...

LOL i didnt even realize that you had picked up on this... well thanks for the try, im still looking for a better way to do tcp commands with timeout but ill have to think harder i guess...

i think ill have my script write or unpack a vb script file and run it, and then communicate the results somehow! kinda feel like im cheating on autoit, ive never had to do this! and is gona kill me seeing as i had been writing a script that operates accross a LAN and i was hoping to make it serverless!

Bump. Has this TCPtimeout issue been fixed? If not it should be imo. I desperately need it for a proxy list checker I'm witting. When a single processed application spends more than 8seconds on a single proxy out of 1000, that is no good.

Hello.

I have the same situation - I need to check ports FROM multiple servers remotely.

I use cycle to do it and list. After that I use psexec to start a remote program

I need to make a commandline tools that check port fast - 3-5 second timeout.

Its really strange that autoit still have no such possibility.

Hey,

i tried the code with the OSWINSCK.dll and it works fine (on xp).

but it doesnt work with win 7 ... did anyone know why?

$runstring = "regsvr32 /s " & @ScriptDir & "\OSWINSCK.dll"
$status = _RunDOS($runstring)

here the return-value is 5 and the $socket then is 0 ...

BPCM · August 12, 2014

I came up with a workaround for this issue; it's not the cleanest solution, but I tried to make it as reusable as possible. Hopefully this helps the next person who stumbles accross this thread like I did.

Instead of tackling this issue with one script, I broke it into two:

TestPort.au3:

#NoTrayIcon
TCPStartup()
Local $socket = TCPConnect($cmdline[1], $cmdline[2])
If @error Then Exit (1)

ExampleScript.au3

#include <WinAPI.au3>

;---This section is optional, but allows you to compile both scripts into one executable
FileInstall("C:\LocationOfTestPort.EXE\TestPort.exe", @TempDir & "\TestPort.exe", 1)
OnAutoItExitRegister("_CleanUp")
;---

ConsoleWrite(_TCPConnectTimeout("192.168.1.12", 3389, 1000) & @CRLF)

;nTimeOut is in millis
Func _TCPConnectTimeout($sIP, $nPort, $nTimeOut = 1000)
    ;If you dont want to use FileInstall change this to the full path of TestPort.exe
    $iPID = Run(@TempDir & '\TestPort.exe ' & $sIP & ' ' & $nPort, "", @SW_HIDE)
    $hPID = _WinAPI_OpenProcess(0x0400, 0, $iPID)
    $nStep = 10
    $i = 0
    While ProcessExists($iPID)
        If $i < $nTimeOut Then
            Sleep($nStep)
            $i = $i + $nStep
        Else
            _WinAPI_CloseHandle($hPID)
            ;Timeout reached; return 2
            Return SetError(2, 2, 2)
        EndIf
    WEnd
    Local $t_ExitCode = DllStructCreate('int')
    Local $avRET = DllCall('kernel32.dll', 'int', 'GetExitCodeProcess', 'ptr', $hPID, 'ptr', DllStructGetPtr($t_ExitCode))
    If @error Then
        _WinAPI_CloseHandle($hPID)
        ;Internal error; return 3
        Return SetError(3, 3, 3)
    Else
        _WinAPI_CloseHandle($hPID)
        ;return exit code of our port tester
        Return DllStructGetData($t_ExitCode, 1)
    EndIf
EndFunc   ;==>_TCPConnectTimeout

;Only needed if you are using FileInstall
Func _CleanUp()
    FileDelete(@TempDir & "\TestPort.exe")
EndFunc   ;==>_CleanUp

TestPort will need to be compiled first since it is called by ExampleScript. Any time you run _TCPConnectTimeout(), it will create a child process, wait for it to finish the connection, or close it if it has taken too long.

Returns:

0 Success

1 Connect failure

2 Timeout reached

3 Internal Error

Hello.

The issue due to some fellow from a different forum is that Autoit network functions use *BLOCKING* ports. These use the *WINDOWS* network default timeouts.

I've mentioned in the bug / feature request system quite a long time ago to modify the functions of Autoit, so that they do *NOT* always open blocking ports, but non blocking ports. Then it would be possible to define really short timeout periods.

The fellow I mentioned above was so kind to write a small EXE for me, that I use with FileInstall() when I need to check port status from autoit really fast.

This is the source code of how this can be done:

program chkPort;
// Input: chkport-ip <ip address> <port> [timeout]
// Output: Text message + Errorlevel
// 0 if we connect,
// 1 if we timeout,
// 2 if we get a socket failure,
// 3 for an invalid address.

uses sockets,inetaux,strutils,winsock2,sysutils;
var
ConSock : LongInt;
sAddr : TInetSockAddr;
timeout : dword;
result : boolean;

procedure setnonblockingsocket( s : integer );
var
nb : dword;
begin
nb := 1; // 1 = nonblocking, 0 = blocking
winsock2.ioctlsocket( s , FIONBIO , @nb );
end;

function is_writable_socket( sck : integer; timeout : dword ) : boolean;
var
fds : tfdset;
tv : timeval;
result : boolean;
begin
fd_zero( fds );
fd_set( sck , fds );
tv.tv_sec := timeout div 1000;
tv.tv_usec := timeout mod 1000;

// select (socket+1 , read , write , except , timeout) - wait
// "timeout" to see if data can be written to "socket" without
// blocking

result := select( sck + 1 , nil , @fds , nil , @tv ) > 0;
is_writable_socket := result;
end;

begin
// create a socket, die if we fail
ConSock := Socket(af_inet, sock_stream, 0);
if ConSock = -1 then begin
writeln('Could not open socket: ');
halt(2);
end
else begin

// make it non-blocking
SetNonBlockingSocket(ConSock);

// if timeout defined use it, otherwise default to 2 secs
If paramcount >= 3 then Timeout := numb2dec(paramstr(3),10)
else timeout := 2000;

// fill in the socket info - protocol, address, port
with sAddr do begin
Family := af_inet;
Port := htons(numb2dec(paramstr(2),10));
Addr := StrToAddr(paramstr(1));
end;

// die if we can't turn the address into something useable
If saddr.Addr = 0 then begin
writeln('Could not resolve ',paramstr(1));
halt(3);
end;

// otherwise try to connect
Result := (fpConnect(ConSock, @sAddr, sizeof(sAddr)) = 0);

// and see if it become writeable in the time allowed
result := result or is_writable_socket(consock, timeout);

// close the socket
Shutdown(ConSock, 2);

// and report results
If result then writeln('Port listening')
else begin
Writeln('Port not listening');
halt(1);
end;
end;
end.

You can checkout the compiled EXE here from my dropbox: https://dl.dropboxusercontent.com/u/19989673/ChkPort-IP/chkport.exe
